Hi again, to those who have seen my other threads, yes I haven't been able to bring myself to by a PC just yet, its alot of money lol.
But anyway, I was just wondering if 2 GTX 460s would be more powerful than 1 GTX 560ti?, or a 6950 2 gig? Thanks again. :)
 
That equates somewhere close to, or in excess of a single 580 - so the short answer is yes.

The problem is price: if you end up spending more than what a 1 or 2GB 6950 goes for these days the advantage becomes negligible. There's also the problem of whether you already have a 460 in your possession - if you do, definitely pick up another one. If you don't, you'd be better off with a 6950 or even a 570 if you can find a deal on one.
 
Thanks, 2 460s is only 3 pounds more than 1 6950, and 10 pounds more than a 560 ti, and im pretty sure a 570 is waaay more than 2 460s.
 
I think they come packaged with the cards now.

I'm not 100% on that because I haven't purchased an nVidia card in a while, but the only bridges that likely come only with boards these days are tri and quad-SLI bridges.
 
Stick with the 460. It is faster than the 550Ti There's one problem with SLI/CFX, and that is driver issues. However, the 460 consumes more power.

Also, please refrain from double posting.
 
Don't want to double post again, but it seems to have fizzled out abit, I just need to know if it matters which brand of CPU I use, I want to use an I5 2500K but the board I was going to use with it is and intel chipset, will it still work with SLI?
 
There is an edit button at the bottom right portion of your post that you can use to edit your post.

Secondly, the socket of the CPU and Motherboard need to be the same. The 2500K has a socket 1155, so you have to check that your motherboard is a Socket 1155. Also, you can check by the chipset. The motherboard's chipset should either be H61,H67,P67,Z68, Q67.

Thisrdly, your motherboard should have 2 PCI-E Express slots. These slots usually have a tab at the back of them, which holds onto the GPU.

Whatis the motherboard's model number?
 
Oh yeah forgot about the edit button. The motherboard is a z68 which I just found only supports crossfire so I will have to have a rethink somewhere along the line. Thanks for all your help guys and putting up with my incompetence.
 
Then it's simple. You can get a single 6950 or wait for the new AMD Radeon HD 7xxx series and Nvidia's cards to come out.
 
The 7950 and 7970 are along the expense of a 580 and 6990 at the moment; so that's just outright pointless.

He can wait around for the 78xx if he wants but who knows where that's going to lie on the hierarchy. As for the rethinking bit: unnecessary - MSI has a Z68 board that supports both SLI and Crossfire.

I found an asus motherboard that does the same thing,(I'll look for the MSI one too) so yeah I now plan to buy this motherboard with an i5 and 2 gtx 460s. Thank you everyone!
 
If possible go for a single card even for a few pounds more.
I'm running a SLI system for a while now, and I can tell you a few reasons why YES and why NO.

The NO is first the power consumption as earlier said, not so important for your bill but for the choice of PSU. With two Fermi chip Nvidia cards and a little hardware around them, you should have a minimum of 750W to start with.
Second, not all games support SLI properly, that's why you don't have, in every game the full power. With a single card more likely.
And third, the micro twitching. Which can happen on some setups and looks like very nervous lagging.

The YES is a little bit the price and upgrade ability with maybe one more card later on.
But you should select a proper mainboard for SLI (in my case ASUS), with a good intel chipset or if you go for AMD with Nforce chipset.

Considering what you said, I may have to think on this a little, thanks for your reply.
 
No Problem.
I don't say, that SLI is bad in general, but there are a lot things to consider.
And if you anyways start from scratch, a single GPU setup with the option for SLI/Crossfire is the best solution.
When you have a setup that you would consider, just post it here (MB, RAM, CPU, GPU and PSU, case also if you want) and I will give you my opinion for it. Only if you like ;)

Thanks :), that would be good, and I will when I finally get around to finding the best parts and actually buying them.
